The crash occurred shortly after 6 p.m. Saturday at MacArthur and Eberhart roads.

Authorities on Sunday tentatively identified the victims in the crash as 41-year-old Sharon Gonzalez-Medina, who was driving a car involved in the wreck, and a 16-year-old boy, whose name was not immediately released. Both are from Whitehall.

Whitehall Township fire Chief Robert Benner said the crash occurred when a pickup truck speeding north hit Gonzalez-Medina's car as it was turning left onto MacArthur Road from Eberhart Road. The car was pushed across MacArthur Road and caught fire, Benner said.

Whitehall Township police ask anyone who might have witnessed the crash or has information about the crash to call 610-437-3042, ext. 113.
